JESSE G. VINCENT, O1 DETROIT, IICHIGANQASSIGNOB '10 I'ACKARD MOTOR CAB COMPANY, OF DETROIT, MICHIGAN,

Toatt whom it may concern:

Be it known that I, JESSE G. VINCENT, a citizen of the United States, and resident of Detroit, Wayne county, State'of Michi an, havev invented certain new and useful Improvements in Motor-Vehicles, of which the following is a specification.

This invention relates to motor vehicles and particularly to the water circulation system of the motor.

One of the objects of the invention is to simplify the piping of the water circulation system of a vehicle motor.

Another object of the invention is to provide a water jacketed intake pipe for a hydrocarbon motor whereby the gases pass ing to the motor are heated by the water passing from the cylinder jackets.

Another object of the invention is to provide a novel construction of intake pipe connecting the cylinder blocks of a V-type motor.

' Other objectsoi the invention will appear from the following description taken in connection with the drawings which form a part of this specification, and in which:

Figure 1 is a side elevation of the forward part of a hydrocarbon motor, together with the radiator and water circulation system as adapted to a motor vehicle, parts being broken away to show internal construction.

Fig; 2 is a transverse section and partelevation of'the motor shown in Fig. 1; and Fig. 3 is a plan view of the intake pipe A illustrated in the other figures.

Referrin to the drawmgs, 10 represents a hydrocar on motor having two blocks of c linders 11 arranged 'side by side. As s own, U V

cylinders are provided with the usual water the motor'is. of the vtype and the jackets, 12. he cylinder bodies and their heads may be made integral if desired, but in the form shown the heads 13 are formed separately and secured to the cylinders as by bolts 14:. The heads are also water jacketed and are formed with water outlets 15, adjacent the. middle of the cylinder blocks. The heads and cylinder blocks are also cored to .form intake passages 16 leading from a middle point as at 17 to the various intake ports 18 which are controlled by valves 19. It will be understood that there are two of these inlets 16 side by side adjacent the middle of each block and one of the passages 16 therefrom leads to the intake to the ends thereof -p1pe somewhat and therefore,

Specification of Letters Patent. Patented J 1 522, 1920. Application filed September 16, 1818. Serial No. 120.501.

passages 16 are of a peculiar curved con structlon a depression or pocket 16 being provided below each intake port 18 for the collection of the condensed fuel. As will appear from an examination of Fig. 2 these pockets are so formed that the condensed fuel will not impede the passage of the intake gases.

An intake pipe 20 of novel construction connects across from one cylinder block to the other. This intake pipe is of arched construction as shown and it isformed with two independent passages 21 and 22. The passage 21 is for the intake gases that enter the passage through an opening 23 at the middle of the pipe, the gases being supplied by a carbureter 24 suspended from the intake pipe between the cylinder blocks. This passage 21 extends lengthwise of the pipes and it is bifurcated or divided by a wall 2 as it approaches the end of the pipe. T us there are two outlets 26 at each end of the intake pipe, and these outlets are adapted to communicate with the inlets 16 hereinabove described. Thus the gases entering through the port 23 are divided by the partition 25 and pass through the outlets 26 into the passages 16 formed in the cylinder blocks.

The passage 22 is shown as outside of the passage 21 and it extends lengthwise of the intake pipe from an inlet 27 at each end of the pipe to a single outlet 28 at the middle of the pipe. The inlets 27 are in communication with the outlets 15 from thecylinder water jackets and the hot water from the cylinder jackets therefore passes through the passage 22 to the outlet 28 heating the intake vaporizing or assisting in vaporizing the'gases in the passage 21.

At one end of the motor is a radiator 29 of any suitable form-and a fan 30 driven by the motor is intended for increasing the circulation of air through the radiator. .Between the lower part of the radiator 29 and the water jackets 12 of the cylinder blocks is a pipe 31. This pipe is branched at 32, one branch going to the right hand cylinder block and the other tothe left hand cylinder block. The cross pipe is shown at 33 in 2. j ny suitable water circulation means such as a pump 34 is arran ed in the pipe 31 so that the water may be rawn from the radiator 29 and forced .into the cylinder water jackets.

A water connection 35 extends from the water outlet 280i the intake pipe 20 to the upper part of the radiator 29, and a thermostat 36 is arran ed in the upper part of the radiator or in this water connection to control the flow of water through the radiator. The thermostat 36 and the valve 37 which it controls may be of anv desired form and as shown the thermostat operates the valve 37 to the right when it contracts and thereby closes the port 38 from the pipe 35 to the radiator. Ihis causes the water from the pipe 35 to flow through a bypass 39. which leads downwardly to the pipe 31 at the lower part of the radiator. As the thermostat 36 expands it moves the valve 37 to the left and closes the opening 40 into the b pass 39 and opens the port 38 into the ra iator.

By the above arrangement and location of the thermostatic valve, it will be seen that the flow of water throughthe radiator is controlled by the temperature of the water which has just left the water 'ackets of the motor and intake pipes, whic is desirable in a motor of this type.

It will be understood that the water is circulated through the system by the pump 34 which draws the water from the radiator and forces it into the cylinder ackets where it is led through the passage 22 in the intake header 20 through the outlet 28 and the water connection or pipe 35 to the top of the radiator. Here it is either passed downwardly through'the radiator or through the bypass'39 depending upon the temperature of the water at that pomt.

It will be further understood that other forms of'the invention may be made without departing from the spirit or scope hereof.
